your bugati's just yet. they have to do it a second time to get in the world book of records. it cost $1.8 million i am here to talk about innovations that can change lives. we are going to explore the intersection of hardware and humanity and doing it in a unique way. this is a show about science by scientists. let's check out our team of hardcore nerds. lindsey miran is a cia operative and analyst. tonight, high tech crime stoppers. shots fired in the night. cops pinpoint the crime scene. how do they do it? the new science of solving crime. crystal dilworth is a scientist. if you think wine making is old school, think good. the newest ways of making wine. >> a neuro scientist and i will

phil tores, an entimologist. the by onic arm. see how it's more man-like than machine. that's our team. now, let's do some science. >> hey, guys, welcome to techknow where we bring you stories of innovation here in america. i am phil torres. i am here with michelle, crystal and lindsey. you went to one of the most violent cities in america to see how technology can help us fight crime? >> that's right. i went to oakland, california which has the 5th highest crime rate and nearby richmond which is among the top 20 to look at some very innovative technology that they are looking to

increase the eyes and ears of the police force on the street. so let's have a look these are streets. >> i am not violating any law. >> in two san francisco bay area cities known for crime oakland and rimmond westbound. >> but now, police in both of these cities have high tech back-ups. electronic ears listening for gunfire, 24/7. he lectronic eyes monitoring police and perps alike. even the cars on this street. officer chris tong is patrolling

the streets of richmond that. ding you hear is the sound of a license plate reader. watch what happens when he passes a stolen vehicle. >> it's just triggered on an unoccupied vehicle. turn around and take a look what we've got here. >> the unoccupied vehicle was a stolen nissan sentra caught by the high-speed infrared camera, a series of computer algorithims identified the vehicle's license plate and checked it against a database of wanted cars all in a matter of seconds. >> license plate reader keeps track of a lot of the information that the vehicle was indeed stolen when the vehicle was reported stolen, when we located the vehicle. center. >> these cameras scan several hundred to a thousand plates an hour. much more than an officer could do in a shift.

multiplier. >> captain ursey joiner, iii has been with the police department 23 years. >> we are an agency back in 2010 had 830 sworn police officers. right now, we are hover be around 614 and it's not getting better in the near future. i do have to be more efficient and technology is definitely going to be the key now and moving forward. >> what if you have outstanding parking tickets, say, or speeding violations? flagged? >> no. we only flag vehicles that are actually wanted for very dangerous crimes such as stolen vehicles, robbery vehicles, things along those lines. >> okay. officer brian hernandez was one of several unitssponding to a call about a suspect in east oakland, wanted in a robbery and attempted murder. >>

good. but our cameras weren't the only ones catching the action. each officer wore one of these, another set of eyes, reporting everything that happened. >> shoes or anything on? >> i'm sorry. >> hold on. now. back. sit down. come on? >> i can't talk to my son. >> give us a second. we will let you go talk to him. >> that's totally unrelated. >> oakland is more than 3500 police departments nationwide using body cameras. they have been taking the plates of dashboard cameras because they go where the officer goes. >> officers were able to capture individuals either discarding firearms or making incriminating statements in regards to their involvement until crimes that would have been the officer's word against the subject's word but the lapel camera made this clear and evident. >> our policy is if you are investigating any kind of crime

or there is a potential of an encounter with someone in detention, we are supposed to activate it. >> how has the lapel camera affected your job at all. >> at first, it's a little uncomfortable to have everything recorded but to have the video to back up our work, it's great. >> 703976. >> how are you doing, man? >> do you have your driver's license? registration? okay. >> what happens to the video camera? >> at the end of the officer's shift, he or she plugs it into a terminal and the video is then uploaded onto a network server. the officers can't delete it or anything along those lines. >> a ticket, date and time. sign at the bottom. hidden on roof 207s and light poles is a network of high-tech ears, acoustic sensors that could be a game changer in reducing gun violence. they are part of a gun-shot detteection system called shot

shot spotter" within seconds after a gun is fired, the system pin points the location and alerts please dispatchers and patrol units. >> the first thing it will show will be the fact that there were multiple gunshots fired with a pin-point location within a couple of yards or so. so as asponding officer, i have almost realtime information as to where shots are being fired right now and where i am going. >> here is how it works. when a gun is firedthe sound is picked up by multiple sensors placed in different locations. each sensor records the exact time it detected the shot. shot spotter uses those times and the distance between each sensor to determine the location of the gunfire. >> gunfire travels a great distance. one or two miles. and if you have sensors far apart, then only the strongest sounds that have gunfire will get to several sensors.

>> how did the idea for shot spotter come about? >>ists working at a place called stanford research institute, sri, in mineral park. right next door, we had a very severe gunfire problem and i thought that my expertise in radio wave could be used to show the police exactly where gunfire was. >> this is shot spotter's incidents review center. in. >> reviewers from 40 countries around the world. >> tell me what happens. walk me through it. >> the first task is to look at where that shot took place and what kind of other information he or she can pass along to thesponding officer. >> now all of what we would normally do in an incident takes place in 20 seconds on average. >> now from close by, and that was 300 feet away, it's a little

hard to tell what's going on. but further and further away, you can hear that halfway through this, there is some other noise that the same loudness and, in fact, what that is a second person shooting this produces a different response pattern for police. it's exactly the sort of thing you cannot find out on 911. >> have you encountered any public concerns about privacy once they find out there are these sensors all over theplace? >> we put a lot of effort designing sensors so that they cannot be used as elicit eavesdropping devices. it has to be an impulsive noise. >> has shot spotter changed the oakland? >> it's definitely been a huge part of not only our response to gun violence but, also, trying to basically tell and predict where gun violence is going to be and have some type of follow-up.

i am a firm believer if you can track it, you can predict it and if you can predict it, you can prevent it. >> nobody wants to hear the chatter of gunfire and wondering if the next bullet will come through their window accidentally. now, instead of shots being fired being normal, shots being fired means cops are coming. that has been an encouragement to citizens. they say the police are doing their part. we are going to do our part. >> how are you doing? >> we can squash it in our community. >> i am really impressed with how precise this technology is. >> are there any concerns about civil lib we can at this? >> there are. there are quite a few concerns. there certainly is the concern that this is sort of one step closer to big brother society, that there are these sensors all over the city, and people are concerned about that. in fact, they have now developed an indoor technology, and they

are planning to use it inside schools. there is a charter school in oakland that is going to use the shot spotter technology within their school. >> there you go. >> you have an interesting piece of technology you are going to show us. >> yes. so i got to do a piece looking at by onic arms. these are robots in place of your hands. it was pretty incredible. break. >> we want to hear what you think about these stories. join the conversation by following us on twitter and at aljazeera.com.

>> aging america continues... healtly retirees lending a hand to their aging neighbors. >> it's been tough gettin' old... >> a story of humanity and dignity. >> everybody needs a little bit

of help sometimes... >> we can do it! >> on al jajeera america skwlfrn. >> welcome back to techknow. i am here with richelle, lindsey and phil. you were about to tell us about new technology. >> imagine you guys lose an arm in an accident. you may think your life will just never be the same. but i got to check out these robotic hands that have completely revolutionized how people can live their life. let's take a look. it's a an early scene played out in-households everywhere. besides getting his kids dressed and dropping them off at school, jason coburn must get himself ready. that means making important decisions about what he is going to be wearing

today. >> being a bilateral amputee, you have to use prosthetics. if you are a single-arm amp tea, you have the ability to use a real hand to help, you know, it's kind of like a tool for them. >> near san diego, california, katie walker is putting her newest tool. this para olympic hopeful is trying out prosthetics field. >> the difference is the little wrist unit. it actually pops off. >> all right. >> and actually, the handle goes right inside of here. so, it's supposed to, after i swing, after i follow through, you just pop it right off. >> then run? >> then start running. >> and rotate around. cool. >> for upper-limb amputease, gone are the days of hook and cable arms.

in labs like this one at advanced arm dynamics outside dallas, texas. technicians work alongside therapists to custom design dreams. >> really cool to have an opportunity to see a patient, see what they need and actually do what they need, not just say, well, all we have is this. i'm sorry. here you go. so we get to be really creative. >> now, thanks to electronic add veeps, the technology brings patients closer to the experience of experiencing the hand mobility most of us take for granted. one of the most sophist cases, the ultra revolution allows users to move through a series of grips, even the ability to rotate the thumb. there is even an app for that. >> let's put these electrodes you. measuring? >> these are sensing your muscle contracting. you are now by onic.

>> i am now by onic. so powerful. >> right now, i should be able to control this robotic hand just by moving my muscles. >> did you see that big red spike? the han the hand is operating. i want you to make a closing. that was blue. >> inside the hand is powered by an intricate cat network of tiny wires attached to six motors that allow each finger to art articulate separately. 24 grand rapids are possible with a total grip force of about 7 pounds. the arm is powered by a battery with an 18-00 cycle or charge. >> that's been extended by up to 25% in the ultra revolution. >> what is the most challenging part of this technology? >> it's matching the technology with the patient. we want to pair technology with the right type of patient. >> how is it going? katie is working with our team up in portland. she was born without her hand.

so she is worn prosthetic devices throughout her life. she's gotten interested in the para olympics. she wants to do track and field. >> how does is it different than the one you would normally use? >> it's much lighter. made of carbon fighter and the socket is comfortable and sweat-proof and actually, it's made for this starting block. so, it helps me get down. i will show you. >> on your mark, getset. go. >> katie was born in taiwan with a congenital condition. like many amputeas who have grown up without, she was concerned about comfort. >> yes. >> what was the reason? >> i knew i was going to college. i wanted people's first impression of me not to be a person with a disability or an amputation but, also, wanted to

see how it would feel like to have two hands or the closest thing that i could. >> the island technology is the closest many patients can come to the dexterity of a real hand. for jason possible? >> i am going to try. >> despite having lost both of his arms in an electrical accident, he is willing to try just about anything sometimes using his more durable hooks around the farm. other times, with his ilimbs. he has become al fuel tester, making him one of the first people in the entire world to have two by onic arms. >> jason is one of those rare birds that has not only the motivation and the will to move forward but he has a great personality. he is willing to talk to other people about his experience, what he has been through, the good, the bad, the ugly. >> where would you like to see the technology go? >> they told me things that they

are wanting to get into single nerves. they are wanting to be able, one nerve to move one finger. >> it's called target muscle reinnervation where a target muscle is denervated and then nerves from the reds i had annual limb are harvested and transplanted into that area. if it social security successful, sensor electrodes will send signals directly to the artificial limb allowing the hand to perform multiple taxes simultaneously and intuffitivelntuitively. >> they are starting to implement that. eventually it will will make out to a human being. >> until then, katie walker's training hard for the 100-meter sprint. she hopes to compete in the 2016 paralympics until brazil. jason is searching for the next do. >> i try to inspire people every day because i think people give up way too easy. i do what i do.

i am not super superman. i am jusjason. >> we love watching this and seeing how technology can actually, like, help people feel more human. when you think about it, it's like cold and technical, like inhuman sort of machine. but it was helping people to do things that made them feel like participate. >> thanks, phil. that was such a cool story. crystal, you've got something interesting coming up for us. >> my story will make all of you a little bit jealous. i got to study how technology is being applied to wine making. valley. >> we will check that out after this. >> every sunday night, al jazeera america brings you conversations you won't find anywhere else... >> your'e listening because you wanna see what happen... >> get your damn education... >> talk to al jazeera only on al jazeera america >> oh my... to it.

>> guys, we will back to tech know, i am phil torres here with richelle, crystal and lindsey. crystal, you got to do a pretty classy story. valley? >> i did. i visited shaffer vineyards. and they are using technology and application of realtime data

in their wine making process. you know see here some of the amazing different processes that they use. let's check it out. here on the hillside in napa, these pickers are harvesting grapes the way it's been done for thousands of years: by hand. 20th century technology has a hand in almost every step of the process from vine to wine. >> i am an innovator when it comes to making the best wine possible, whatever it takes. doug shaffer is the president of shaffer vineyards. he has been working here since 1973 when his father bought the estate. wine making, experience,

innovation, technology, computerization, able to get more information, better information to make better decisions with. >> for the last 29 years, his partner in making those decisions has been alia maker. he gave me a tour of the vineyard's high-tech tools fine tuning his craft. >> this is our weather station they gather ter detailed data in the field and transmit it via phone. >> what kind of analysis do the computers do? >> it gives us the temperatures, the wind speeds throughout the day, humidity throughout the day. and allows us just to have a feel for what's going on here for these vines. >> the second system called fruition gives alias a real-time view of what's happening inside the vine. what we have been here is a

thermo cupler right in this area here with the solar producing plant. >> as water moves through the plant, the thermal coupler tells the grower how much water is in the vine. it tells us if the vine is in a deficit or doing fine. >> with this, we can actually save water, which is an important thing. >> especially in california which seems like its been in remember. >> by eliminating water at the right times and by giving water at the right times, we can have those berries grow small. the smaller the berries, the buser the skin to juice ratio is. that means more robust, big, juicy wines. >> innovative technology also fine tunes the work at the crush pad. here, alias programs the optical sorter to choose grapes based upon a specific color.

only the right ones. everything else gets dump here we notice the change almost overnight. the wine is only 5 or six days old. fresher, cleaner, more focused. it was we are going to check out a red wine ferm entation. >> what was sorted earlier? >> it looks look luke soup. >> they communicate with alias via wi-fi. >> if it gets too hot t will send me an alarm. fe fermentation team. >> i get a text and phone call. i have them at 2:00 in the morning sometimes. >> even the aging process it is technology. >> this was invented by nasa as

part of their space station, so what it does, it actually purefies the air using the photo catalytic oxidation technology. >> using light? >> exactly. >> to explode anything that would be alive in the air? >> basically will destroy any mold, yeast, anything that can do damage to barrels and kegs. so this is our current release, 2009. >> the quality of the wine has to do with the instinct of the wine maker that was in charge. new technologies take allegations away from that, that instinct and putting in a lot in the hand of data analysis. >> i had been on this property for over 29 years now. so, i used a lot of that instinct, so i used the technology to back up what i feel. it just as to the whole picture so that i can make better

wine. >> my question, crystal: did you bring us any sample? >> umm. well, i have a bottle for me. but nothing is -- that's worth more than my car. myself. >> amazing stuff today, guys. thank you for your stories. we will see you again next week on "techs know." dive deep into these stories at >> this is al jazeera america. i'm tony harris. leaders of the euro maidan

movement, and in the eastern part 69 country protesters are back in the street with scuffles between pro-russian and anti anti-russian demonstrators, and russian conducting military drills on the border congress accusing credit suisse of a scheme to help customers, using cloak and dagger tactics so customers could evade the irs. two men who killed a british soldier learned their fates. one man got life in prison and another 45 years. they riddle lee rigby by running him over with a car and then it happened in the middle of a

day on a busy street in london. the air in china is so thick with smog. the pulsome call the air pollutn china very concerning. we have more news next hour. so i have a voice and i use it. >> hip hop pioneer and business mogul russell simons is a man of vision. >> you can't fail until you quit. >> music, fashion, social action, the def jam founder is a pervasive cultural influence and a strong advocate for justice. >> the war on drugs has done more to detroit the fabric of the black community than anything that we can think of. not the effects of jim crow and the effects of slavery, it's the war on drugs. >> he's also a practicing yogi, who values daily medication. it's the subjects of his latest
